* A new poll from the University of Washington shows Sen. Patty Murray (D) leading state Sen. Dino Rossi (R) among likely voters, 46% to 40%. Among registered voters, however, Rossi currently has the edge, 42% to 39%.

* Most expect Chris Coons (D) to have a very tough time against Rep. Mike Castle (R) in Delaware’s U.S. Senate race this year, but Democrats aren’t giving up. Vice President Biden, whose former seat is at stake, said yesterday he would host a fundraiser for Coons later on June 28.

* In North Carolina, the latest survey from Public Policy Polling shows Sen. Richard Burr (R) leading his Democratic challengers by 7 and 11 points, respectively. Rasmussen says Burr’s edge over Elaine Marshall or Cal Cunningham is even bigger.

* And last week, Gallup showed Republicans jumping out to a six-point lead on the generic congressional ballot. Those results now look like an outlier — Gallup’s new results show the parties tied against 46%.
